Answer:
a(n) = 1 + 7(n-1)
Step-by-step explanation:
For this case we have the following equation:

If we multiply both sides of the equation by 3 we get:
---> Multiplication Property of Equality
Applying the distributive property we have:
---> Distributive Property
Adding 1 on both sides of equality we have:

---> Addition Property of Equality
Subtracting
on both sides we have:

---> Subtraction Property of Equality
Finally, dividing by -4 on both sides we have:

---> Division Property of Equality
(3/5)(2/5)=6/25

Answer: Rational
Step-by-step explanation: 12 is a rational number because it can be expressed as the quotient of two integers: 12÷ 1
Answer:
A) 5
Step-by-step explanation:
distance = √(distance between x coordinates² + distance between y coordinates²)
the horizontal distance between the two points is 4
the vertical distance between the two points is 3
to prove this, if you started at Q and went 4 points right and then 3 points up, you would get to P
distance = √(4²+3²) = √25 = 5
